Quite often people are faced with the necessity of cleaning products (both gas and gas condensate wells), gas-pumping equipment and protection of valves against drops of moisture, solids and hydrocarbon condensate.To solve these problems, and was created by equipment having the name "gas separator".It is included in the compressor stations, plants that perform complex gas treatment, gas distribution, and collection points, gas processing plants.
gas separator can be both independently and section performance.
Normally the separator is divided into three parts: pre-separation which separates most of the impurities;drip, which is collected and pre-assembled liquid settles;and kapleulovitelnaya that cleans gas from the smallest liquid droplets.
gas separator is equipped with devices allowing to control the temperature of the gas, the pressure and liquid level.
Types of equipment are classified as follows:
- the nature of the forces that affect the gas inside the device, allocate inertia (a packing), gravity, and mixed-type centrifugal separator;
- on the Status of separators in space and by their geometric form, there is a cylindrical (horizontal, vertical, oblique) and spherical separator;
- on location for the collection of separated liquid, devices with remote and are located within the volume of the gas separator collections;
- largest operating pressures are high (more than 2.5 MPa), medium (0.6 to 2.5 MPa) and low (less than 0.6 MPa).
gravitational gas separator operates on the principle of reducing the speed of the gas located therein to a point where the impurities therein are, due to gravity settle.Such devices are structurally simple, but bulky and metal content.The separation efficiency is from 75 to 90 percent.
And what is an inertial separator gas, what is its principle of action?
It impurities settle because of repeated rejection by means of special nozzles of the gas flow.These nozzles are made of a different configuration of plates and gaskets coalescing filter materials.The most frequently used mesh and louver section.
efficiency of the separation is between 95 to 99 percent.In centrifugal separators of gas impurities are deposited on the walls of the housing under the influence of centrifugal forces generated during rotation of the flow in the annular or cylindrical separation chamber.
most advanced direct-flow centrifugal gas separators and the multi-single-threaded types can achieve efficiency of particulate matter from 98 to 99.5 percent.Plus - and metal smaller than that of its inertial and gravitational counterparts.The throughput capacity of up to 15 million cubic meters per day at a pressure up to 16 MPa and a temperature of minus 40 to plus 100 degrees Celsius, and the starting liquid content of from 1 to 200 cubic centimeters per cubic meter.
Guidelines for reducing metal separators and efficiency - is the use of mesh nozzles coagulation of the aerosol contained in the filters, improved aerodynamic flow in the separation chamber, the use of separator column type and multi-purpose.
centrifugal separators are industrial equipment designed for the separation of a gas stream, which uses centrifugal type of separation.They belong to the equipment used for the purpose of swirling flow of multicomponent gas separation systems.
